vMy invention relates to machines for securor other cleaning implements,and an ob'ect of my invention, among others, is thepro uction of amachine of this class that shall be particularly efiicient for suchurpose.

One form of machine embo ying my invention and in the construction anduse of which the objects herein set out, as well as others,

-may be attained, is illustrated in the accompanying drawings, in which-I Figure 1 is a plan view of my improved machine. Figure 2 is a View inside elevation with parts underneath omitted.

Figure 6 is a detail View illustrating a binding strip with corrugatedsides for straightening up the fibers.

In the accompanying drawings the numeral lO indicates a table of anysuitable construction and upon which my improved machine may besupported, said machine comprising a base plate 11 for machine arts thatare secured to and rest thereon. hese include supports 13 secured to andrising from the plate 11 near opposite sides thereof and a driving wheelsupporting bracket 14 secured to the side of one of said supports toreceive a driving wheel supporting stud 15 secured to and projectingtherefrom and having a driving wheel 16 with a driving inion 17 securedthereto rotatably mounts on said stud, the driving wheel being suitablyarranged in any desired manner to receive a belt as a means for drivingit. The pinion 17 meshes with a driving ear 18 on a feed shaft 19mounted atone en in a feed shaft supporting bracket 20 secured to theside of one 7 of the supports 13, said feed shaft alsobeing rotatablymounted in feed shaft supporting blocks 21 secured to the base plate 11,and as shown in Figure 3 of the drawin Feed belt supporting arms 22 areadjusta 1y pivotally supported at the ends of the supports 13 oppositesaid feed shaft, and feed belt sup porting studs 23 project from saidarms toward each other to receive pulleys around whlch pass supportingfeed belts 24, the opposite ends of said belts being supported by.pulleys secured to the feed shaft 19.

Retaining feed belts are supported to overlie the belts 24 to retainmaterial, as fibers, thereon, these belts 25 being supported at one endon pulleys mounted at 0 posite ends of a retaining belt supportin shaft26 located in a shaft supporting brac et 27 adjustably secured to asupportin bar 28 attached at its opposite end to t e sup orts 13, theopposite ends of the belts 25 eing supported on pulleys mounted on studshafts projecting toward each other from retaining shaft supporting arms29 secured to and pro jecting from the inner side of the supports 13,and as shown in Figure 1 of the drawings. Core feed supporting arms 30are mounted at one end on the bar 28, the opposite ends of said armsreceiving the ends of a shaft rotatably supporting a sleeve to behereinafter specifically referred to and to which a core supporting feeddisc 31 is secured, said disc having a peripheral groove to receive awire 32 that is incorporated as a core in the structure that is formedin the machine. A- guard 33 is located about a portion of the peripheryof the disc 31jto retain said wire in the groove in the disc, and atensioning device 34 of any suitable construction may be employed topreserve a proper tension on the wire 32.

In the operation of the machine thus far described a binding strip 35,of V-sha e in cross section, and of indefinite lengt is passed into andthrough a tube 36, emerfi'ng therefrom and adacent to an assembly w ee37 mounted upon and to rotate independently of the shaft '19. Thisassembly wheel comprises an important feature of my invention and it hasan assembly groove 38 and fiber adj usting teeth 39 arranged in tworows, one row on each side of the groove 38. These teeth are preferablypointed and taper to a wider dimension at their bases, and the strip isprojected into and through said-groove on one sideof the wheel 37.

The delivery ends of the feed belts 24 and 25 are located adjacent to'thassemblywheol 37, and fiber guides 40 are secured to the fiber shaftsupporting blocks 21, and project upwardly on opposite sides of theassemby wheel 37, these guides being inclined in a direction crosswiseof said wheel to engage the fibers as they are moved along and bend themso that their opposite ends on the outer sides of the wheel 31 will beclosed toward each other, said fibers being held at their centers by thewire 32 within the groove in the binding strip 35 during such bendingoperation.

The binding strip 35 with the fibers held by the wire 32 therein isdrawn through a groove in the assembly wheel 37 by mechanism to bepresently described, said wheel being rotated by the movement of thestrip 3 along and within the groove in the wheel. As

the fibers are moved into the angle between the approaching curvedsurfaces of the bottom of the groove in the wheel 37 and the wire 32there is a tendency for the fibers to be crowded backwardly and theteeth 39 are,

therefore, provided to counteract this tendency and maintain the fibersin or restore them to an upright position. Other means may be providedto effect this result, for instance, as by corrugating the wall of thebind ing strip 35 in the direction of depth thereof and as indicated bythe numeral 69 in Figure 6. i

Compressing wheels 41 are secured to shafts 4 243 rotatably supported bya. bearing block 12 secured to and rising from the top of the table 10.The shaft 42 has its hearing formed directly in the block 12 while theshaft 43 is mounted in a bearing in an adjustably mounted block 44located in an opening in the block 12 and with its lower end restingupon the table 10. Gibs 45 overlie the upper end of the block 44 andform the upper side of a guideway in which the block 44 has a slightmovement to compensate for various thicknesses of material passingbetween the wheels 41. The opening in the block 12, just hereinabovereferred to, is closed at one side by a cover plate 46 that is securedto said block as by means of screws. A hearing bracket 47 is secured tosaid block 44, and a compressing wheel driving shaft 48 is mounted inbearings in the lower ends of the plate 46, the bracket 47 and a similarbracket 63 secured to and projecting from the side of the block 12, asshown inv Figure 3, and below the bottom thereof. Said shaft has bevelpinions 4950 in mesh with bevel pinions on the lower ends of the shafts42 and 43. The pinion 49 has a hub rotatably mounted in the bracket 47and said pinion is splined to the shaft 48 so that in the adjustingmovement of the block 44, saidblock, the shaft 43, and bracket 47, aswell as the intermeshing pinion, move as a unit.

The shaft 48 is driven by a. bevel pinion thereon in mesh with abevel'pinion on a con- 'necting shaft 51, the latter having a gear 52 inmesh with a pinion on a driving shaft 53 mounted in bearings on thetable 10 and driven as by means of a belt engaged with a driving pulley54 secured tosaid shaft.

An adjusting bar 55, secured at one end to the block 44, passes looselythrough a hub 56 on the cover plate 46, said bar at its opposite endbeing loosely secured to an adjusting lever 57 pivotally mounted inbearings 58 in a bracket secured to the side of the table 10, and asshown in Figure 1 of the drawings, said lever having an arm projectingunder the table to the opposite side thereof and havshown. The bar 55 ismounted loosely enough to permit the lever 57 to swing on its pivot, andthe arrangement just described provides means for pressing one of thewheels 41 into yielding contact with the structure passing between saidwheels and being formed thereby, so that one of said wheels may yield tocompensate for any variation in thickness of the material passingbetween the wheels, and yet at the same time exert pressure enough toaccomplish'the purpose for which it is designed.

The formed strip60, comprising the binding strip 35, the wire 32 and thebristles or fibers 61, all tightly compressed with the fibers and wirefirmly secured within the binding strip, passes through a guide 62 afterwhich it may be disposed of in any suitable manner, as by being cut intosuch lengths as may be desired for the formation of brushes or similararticles.

A feed disk supporting shaft 64 hereinafter mentioned is permitted avertical adjustment by reason of the pivotal support of the arms 30, thedisk 31 in operation resting upon the wire in the groove in the disk andsaid wire resting upon the fibers in the binding strip 35. The fiberswithin the binding strip therefore receive the weight of the disk, theshaft 64 and the arms 30 and parts carried by said shaft and including aguard support 65 carrying the guard 33 and a block 66 supporting the arm67 at the end of which the tensioning device 34 is'located.

Stops 68 in the form of screws project downwardly from the upper ends ofthe supports 13, against the shaft 64, and these stops may be employedto prevent the disc 31 from moving too far away from the binding strip35 and the fibers therein, said stop screws therefore preserving theproper amount of pressure of the feed disc upon the mass underneath it.

The wheels 41 are provided withperipheral teeth that engage the fibersto prevent backward inclination thereof at the time of compression ofthe fibers in the stri 35 and in a manner similar to that hereinbe oredescribed as to the wheel 37, the teeth of the wheels 41 meshing onewith'the other, and as shown in Fig. Bofthe drawings, this comprisinganother important feature of my invention.
